Brief notes on the importance of the course and how it fits into the curriculum Wireless communications has become essential part in our day to day life. During recent years there has been significant improvement in the field of wireless communication technology and has rapidly evolved from first generation (1G) to fourth generation (4G). The rapid growth of cellular phones, which principle carry voice are now being widely used for communicating data and images. The communication aspects of this subject depends on the fundamentals of communication engineering. To understand this technology, it is important to know in detail, a number of concepts associated with cellular mobile communication. This course is mainly aimed toward senior year students of the ECE discipline, and in particular, for the final year BTech, and first year M.Tech. However, this does not necessarily imply that any other discipline students can not study this course. Rather, they also should delve deeper into this course since mobile communication is a familiar term to everyone nowadays.
